Product overview
Released in 2021 as part of Corsair’s RMx (2021) refresh, the RM1000x is a 1000 W, 80 PLUS Gold, fully modular ATX unit. Corsair’s product page lists ATX12V v2.53/EPS 2.92 compliance and a 10‑year warranty; Tom’s Hardware’s review posted March 30, 2021. Discontinuation isn’t stated; Corsair currently marks the page Out of Stock.Sourcecorsair.com
Tier: enthusiast — a high‑wattage, Gold, fully modular supply built to power high‑end single‑GPU rigs with extra headroom. It’s well‑suited to high‑end GPU builds and headroom/overclocking in full‑size ATX cases. Note it lacks native 12VHPWR/ATX 3.x; if needed, use Corsair’s Type 4 12V‑2x6/12VHPWR cable sold separately. Unique: a 135 mm magnetic‑levitation fan with zero‑RPM mode.Sourcecorsair.com
